BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 245,858, dated August 16, 1881.

Application tilcdJunc 23, 1881. (Model.)

To au whom fit may concern Beitknown that I, STEPHEN S. NEWTON, a citizen ot' the United States, residing at Binghamton, in the county of Broome and State of New York, haveinvented certain new and useful Improvements inBottle-Stoppers; and I do hereby declare the t'ollowing to be a full, clear, and exact description ot'the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to letters or figures ot' reference marked thereon, which form a part ot' this specification.

Figure 1isavertical section of my improved bottle-stopper. Fig. 2 is a vertical section of a modiication thereof.

In the drawings, A A2 is the dischargingtube, the lower portion, A, beingscrew-threaded to receive the cork-tube D, and provided with a flange, A', to cover the mouth ot' the The upper part, A2, ofthe dischargetube is externally screw-threaded at its upper end, the extreme upper end being closed bya Hat plate, c, in which are formed ports a at some distance each side of its center.

I3 B is a hood,consisting ot' a tube-section, B', and a dat surface, B, adapted to tit over and close the ports a.

I) is a central discharge-port formed in the hood. The exterior surface of the portion A2, which is below the screw-threads, is smooth, to present a more finished appearance when the hood is screwed up to discharge the liquid. than it would present it' the screw-threads extended down to the ilange A'. This construction also permits thc lower edge ot' the tubesection B of the hood to be turned inwardly against the pait A2, as at b2, and engaged with the shoulder formed by the threads, and thus prevent the removal of the hood.

C is a washer fitting closely within the hood, and having a port, e, corresponding to the discharge-port l), and serving to close the ports a. a' closely when the hood is screwed down.

In Fig. 2 I employ an internally-screwthreaded iiange, A3, depending from the flange A', to t upon the neck ot' the bottle, and discharge the liquid through a port, b', i'ormed centrally in the upper part ot` thehood by dispensing with the tip through which the portb is formed in Fig. l, the construction shown in Fig. 2 possessing some advantages over that shown in Fig. 1 when' used for discharging iinely-powdered orother substances which will not ow freely through the tip shown in Fig.1.

a2 is a spur projecting upwardly from the center ot' the cap of the tube A2, in which the ports a are formed, and, entering the ports b', effectually prevents the entrance of dirtat l his point when the cap is screwed down upon the end of the tube A2.

One advantage which results from my arrangement of portsthat is, placing the ports a. in the upper Hat end ot' the discharge-tube A and eccentric to its center, with the discharge port or opening through the cap in its center-is this: I am enabled to use a packing-washer, C, in the cap, whichisheldin place by the screw-threads in such manner that the hole through the washer will be coincident with the discharge port or opening in thehood or tip, the relation of the holes not being disturbed by turning the washer around relative to the hood, as would be the case it' the hood and washer had one or more holes arranged eccentricall y to their centers. Another advantage is that I am enabled to employ a spur which shall project through the port or opening b when the hood is screwed down. Another advantage is, when the hood is screwed down the ports a are closed, thus` preventing liquid from escaping through those ports and thence down between the hood and dischargetube.

I am aware that a patent granted N. D. VVhitin, April 29, 1842, shows a cork-tube constructed with a screw-thread upon its outer end, in combination with an internally-screwthreaded cylinder or cap having a central discharge-port, the cork-tube having a. throat or port in its upper end, which is closed by the screw-threaded cylinder or cap; but there are some objections to the manufacture and use of INhitins stopper which are overcome by my construction. rEhusVVhitinsopeningthrough the cork-tube is expanded at the upper end, thus necessitating the employment of acore with the bulb or head at its upper end in casting it, whereas the interior ot' my dischargetubeis cylindrical and ot' substantially uniform size throughout, thus permitting me to use a cylindrical core with two spurs at one end to for-n1 the ports a'. Again, in Whitins stopper the part B, around which liquid is discharged,

IOO

is placed below the plane of the upper end of the part E, thus necessitating a downwardlyprojecting flange on the tip upon which to mount his packing-washer C, Whereas, from the fact that I close the upper end of my discharge-tube by means of a flat plate, a, through which the ports are made, I am enabled to attach niy Washer rmly to its place Within the hood by means of the internal threads of the flange B', the thread serving as an internal rib,

which engages with the lower edge of the tral port, I), and a flat inner surface adapted to t closely the lat plate a of the dischargetube, substantially as set forth.

2. Intheherein-described bottle-stopper, the combination, with the discharge-tube A, having at its upper end the Hat plate a and ports a', of the hood provided With a central discharge-port7 and the Washer C, secured in place bythe internal thread ot' the hood7 substantiallyv as set forth.

3. In the herein-described bottle-stopper, the combination, with the discharge-tube having' the plate a, ports a', and projecting spur a2 at its upper end, of the hood B B. provided with a central port adapted to receive the spur ft2, substantially as set forth.

In testimony whereof I aflx my signature in presence of two witnesses.

STEPHEN S. NEWTON.
